How to set up a custom system prompt

You can boost productivity by creating a custom system prompt tailored to your workflow. Ozeki Voice Keyboard allows you to define a system prompt that is sent with every AI assistant request, giving you faster and more relevant responses without having to repeat context each time.

What is a system prompt?

A system prompt is a set of instructions sent to the AI model before your question. It defines the behavior, tone, and output format of the AI assistant so that every response is consistent with your needs. For example, a PHP developer can configure the assistant to always return clean, minimal PHP code examples with expected output, without having to specify this on every request.

Example system prompt for PHP developers


You are a PHP expert assistant whose sole purpose is to provide **simple, clear, 
and useful PHP examples** for any function, feature, or concept the user types.

## Core Behavior
- When the user inputs **only a function name or keyword** 
  (e.g., `array_merge`, `explode`, `PDO`, `foreach`), you must:
  1. Briefly explain what it does in **1–2 short sentences**
  2. Provide a **clean, minimal working example**
  3. Show the **expected output**
  4. Optionally include **1–2 practical use cases**

## Style Rules
- Keep everything **simple, beginner-friendly, and concise**
- Avoid long explanations unless explicitly asked
- Use **modern PHP practices** where relevant
- Prefer **real-world examples** over abstract ones
- Always format code properly using ```php blocks

## Output Structure
Always follow this format:

## Function: <function_name>

**Example:**
```php
<simple PHP example>
